Background technology
In industries such as import and export of goods, transport and storage, logistics and dispensings, in order to ensure to be supervised goods safety in transit, general mechanical seal or the e-seals of adopting closes container door, car door or valve.But, mechanical seal poor stability, easily imitated counterfeit; E-seals only has measuring ability, can not meet completely monitoring party especially customs to controlling the requirement of dynamics.In recent years, occurred a kind of safety intelligent lock replacing mechanical seal and e-seals, this safety intelligent lock has electronic lock and mechanical lock function concurrently, and safety is higher, meets regulatory requirements.
Existing safety intelligent lock generally comprises lock housing, and lock housing is made up of spaced first housing and the second housing, and the first housing is connected in side edge one with the second housing.Dead bolt and bolt driving mechanism is provided with in first housing, the sidewall of the first housing is provided with keyhole, first housing is provided with lockhole near one end of the second housing, be provided with in second housing stressed can to the locking bar of lockhole direction movement, when original state, the some or all of of lockhole covers by the top that dead bolt reaches lockhole, key is inserted in keyhole, rotate key, key drives bolt driving mechanism to move, bolt driving mechanism drives dead bolt to leave above lockhole, locking bar is pulled to make locking bar stretch in lockhole, rotate key round about again, now, bolt driving mechanism drives dead bolt to move to lockhole direction and is held out against by locking bar under the drive of key, locking bar is locked in lockhole, extract key, complete and lock, when unblanking, rotate key, key drives bolt driving mechanism to move, and bolt driving mechanism drives dead bolt to be separated with locking bar, pulls locking bar to make locking bar exit lockhole, then key is extracted by rotation key round about, and now, dead bolt gets back to original state, completes and unblanks.Owing to directly acting on bolt driving mechanism after key insertion keyhole, when lawless person wants to destroy safety intelligent lock, instrument can be adopted constantly to rotate in keyhole or beat, will damage bolt driving mechanism, thus causing bolt driving mechanism to lose efficacy, dead bolt cannot connect with locking bar or be separated, safety intelligent lock destructurized, cannot lock or unblank, the ageing of freight transportation and safety are impacted.
